An on-orbit recycling method for a buffer foam of a cargo spacecraft includes the following steps: mechanically cutting a shaped PU foam into foam micro-blocks, and putting the foam micro-blocks into a packaging bag for packaging, where the packaging bag is filled with a foaming adhesive; the foaming adhesive includes a component A and a component B, which are independently packaged in a two-component packaging bag; and the component A and the component B are separated by a film; and squeezing the film between the component A and the component B, such that the two components are fully mixed, foamed and expanded to finally burst the two-component packaging bag, where after the packaging bag is burst, the foaming adhesive expands into gaps of the foam micro-blocks; and in a microgravity state of space, the foaming adhesive expands and fills uniformly in all directions and fully infiltrates the foam micro-blocks.

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.

Disclosed is a cylinder heating device of a conduit forming system using waste synthetic resin, in which a pipe type unit heater is used rather than a bend type heater to prevent heat loss during heat transfer to a cylinder so that waste synthetic resin in the first and second space parts in the cylinder is melted within a short time as well as the quality of a formed conduit is improved.

A method of upcycling fiber reinforced polymer source material by disassembling the source material into sections; planking the sections into longitudinal pieces; separating core material from the source material in the longitudinal pieces to make composite strips; preparing the composite strips; and remanufacturing the prepared composite strips into an article.

The present disclosure provides for articles formed of a filled polymeric resin material. More specifically, the present disclosure relates to polymeric resin materials that include a filler that includes of a mixture of cured rubber granules, foam granules, and/or textile fibers. The filler can be suspended in and/or encapsulated by the polymeric resin material. The polymeric resin material, the filler, or both can include waste or scrap material from manufacturing or from ground post-consumer waste.

Methods of producing particles of fiber and resin from fiber-resin composite materials are disclosed. The particles may be combined with a resin system and optionally combined with fillers, binders or reinforcements to produce new cured solid composite products.

A system, process and resulting product which converts currently non-recycled plastics plastic bottles, jars, containers, PVC tubing, toys, furniture, synthetic plastic carpet and all other plastics that can be shredded, chipped, powered and or melted into a building material or useful utilitarian object. The process eliminates the need for sorting the plastic. The invention only melts the low temperature melting plastic. The low temperature melting plastic act as the glue or adhesive to bond all the high and low melting, shredded, chipped, flaked, powdered, or pelletized plastics together. The listed fragmented plastics must be mechanically mixed before it is subjected to the low temperature melt process. The conglomerate can be processed into a myriad of forms such as construction panels that can also have decorative veneer added. The conglomerate can also be melted, molded into a myriad of shapes that can also be machined to form intricate useful features.

Disclosed herein is a roof cover board and a method of manufacturing an improved cover board product. The method includes receiving waste materials or first use materials, the waste materials or first use materials containing a mixture of cellulose, plastic and other materials; separating the cellulose and the plastic from the mixture; shredding the separated cellulose using a first shredder into a stream of cellulose and shredding the separated plastic using a second shredder into a stream of plastic; selecting a cellulose to plastic ratio from a plurality of cellulose to plastic ratios; metering shredded cellulose from the stream of cellulose and shredded plastic from the stream of plastic according to the selected cellulose to plastic ratio; mixing the metered shredded cellulose and plastic; forming said mixture into a mat; and consolidating the mat into a finished good using heat and pressure.

A package containing polyolefin film having between about 10% and about 95%, by weight of the polyolefin film, of recycled polyolefin is described. The polyolefin film has an Average Hole Count between about 0.0 and about 10.0, according to the Gel Count Test Method. The polyolefin film has an Average Gel Count between about 0.0 and about 100.0, according to the Gel Count Test Method. The polyolefin film has an Average Relative Gel Height between about 0.0% and about 150.0%. The polyolefin film has a Total Spot Count between about 0.0 and about 100.0, according to the Gel Count Test Method.

Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.
